IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 199,190, dated January15, 1878;

November 2, 1877.

To all whom it may concern:

Be it known that we, J osnrn OUSHMAN and JOSIAH B. GUSHMAN, of Thomson,in the county of Carroll and State of Illinois, have invented a new anduseful Improvement in Windmills, of which the followingis aspecification, reference being had to the accompanying drawings.

The invent-ion relates to an improvement in windmills; and consists inthe devices hereinafter fully described, the object being to provide asuitable means for pumping water and other purposes.

In the accompanying drawings, Figure 1 is a perspective view of a deviceembodying the elements of the invention. Fig. 2 is a detached view ofthe vane X, with its attachments.

In the accompanying drawings, A represents the standard or support,which is furnished on its upper end with a plate, B, provided on itsprojecting portion with an aperture, in which the section of pipe orcylinder D is placed in a perpendicular position, and retained thereinby means of an annular collar, E, on said pipe or cylinder, the lowerend of the cylinder being secured by a loop or other convenient means.

Upon and around the upper part of section D is loosely mounted anothersection, F, the lower end of same resting upon the shoulder E, and theupper end carrying the platform H. Thus it is manifest that the lattersection is capable of revolving, and that, when such revolution occurs,the platform H, with the devices secured upon it, receives acorresponding movement.

The platform H may be of any suitable form and dimensions, and issupplied on its front vertical edge with the wheel I, which is moimtedon the outer end 'of axle K, secured upon the upper surface of saidplatform in bearings L, and provided on its inner end with pinion M,which meshes with gear-wheel N, moimted on an axle secured in bearingsP.

Upon the outer face of wheel N, at a suitable point on its radius, isrigidly aflixed the arm R, which receives the lower end of arm S, theopposite end of same being extended upward and pivoted to one side ofrod T, which is retained by guides V, and passes application fileddownward through the platform H and sections D and F.

It is obvious that, when the gear-wheelN is rotated by the wheel Ithrough the axle K and pinion M, the arm 1% imparts a crank-movement tothe arm S, and, as the latter arm is pivoted to the rod T, that alsoreceives a corresponding motion. Thus it is evident that so long as thesaid movement is continued the rod T will be alternately elevated anddepressed, and can, therefore, be effectively employed for pumpingwater, driving machinery, or other purposes.

The guides V are key'ed upon standard W, set in platform H, and hasloosely secured upon it the vane X,-which extends rearward, and isprovided on one side with the segmental guide y, hereinafter mentioned.

In the fork of the lower guide V is pivoted the pulley-wheel to,opposite which is secured a similar wheel, I), in the casing c, keyed onstandard d, which is set in platform H. The purpose of thesepulley-wheels is to receive a rope, e, which passes over them, and hasone end attached to the vane X, the other extending downward through thesections D F, within reach of the operator. Upon the side of the vaneopposite the rope e, and adjacent the guide y, is fastened one end ofthe rope f, the opposite end of which passes over the pulley g, and isfurnished with a counterpoise or weight h.

It is obvious that if the lower end of rope 0 were drawn it would causethe vane X to move toward the pulley b and away from pulley g, therebyelevating the weight k and drawing rope f in the direction in which it(the vane) is moving, which rope in this condition rests in thesegmental guide 1 and is prevented from wearing or knotting; and it isalso obvious that, when the tension of rope e is relieved, the weight71. will automatically draw the vane X back to its former position. Thusit is plain that the said vane can be veered to suit the condition ofthe wind, and the wheel I brought in such position that the wind maystrike it at any angle, according to the wish of the attendant.

What we claim as our invention, and desire to secure by Letters Patent,is-- 1. The wheel N, provided with arm B, in

combination with the arm S and rod T, which is sustained in guides V,substantially as expressed.

2. In a windmill, the wheel I, axle K, and

with the rope e, in combination with the'vane X, furnished with thesegmental guide 3 rope f, and weight h, substantially as specified.

In testimony that we claim the foregoing improvement in windmills, asabove described, we have hereunto set our hands this 3d day ofSeptember, 1877.
